"tri collider update?"

I don't understand this patch.
It talks of a preliminary trimesh/ccyl collider.

But collisions between trimesh/ccyl are already in ODE.
Just run 'test_trimesh' and press 'c'.

I'm not sure about this one, but I would say this patch is incorrect.
Consider, e.g., dCollideSphereSphere()
This func has normal C++ linkage, so extern "C" in the header would
not be appropriate. (The func is implemented in C++, in a .cpp file).

Only if someone wants to call dCollideSphereSphere() from C, you would
need extern "C" tricks, and do the func implementation in C.
